Nicholas Bacon KC4 New SquareThe oracle of costs law, he is easy to work with, collaborative, and gives good commercial advice.

An ‘excellent set with a speciality in costs‘, 4 New Square is ‘a collection of barristers operating in the modern era‘ that are frequently seen in Supreme Court and Court of Appeal costs cases, with representation from silk to junior level. October 2021 saw the conclusion of Ho v Adelekun, the leading Supreme Court appeal case on the question of qualified one-way costs shifting and set-off of costs. The set had representation on both sides, including renowned costs silk Nicholas Bacon KC for Ho, and Roger Mallalieu KC acting for the successful appellant. Benjamin Williams KC also acted in that appeal for the Association of Personal Injury Lawyers, and in another appeal heard in October 2021, represented the former in GEHC v Rosenblatt, the longest ever costs trial relating to alleged misconduct by a commercial firm of solicitors. In another long-running costs assessment Vik v Deutsche Bank, Pippa Manby led by Bacon KC, was on the opposing side to Williams; her busy costs practice has her instructed in inter partes disputes and solicitor-client disputes in the County Courts, High Court and Senior Courts Costs Office. Daniel Saoul KC has a strong costs litigation practice and particular experience offshore, while Robert Marven KC is often brought into major group and commercial litigation on specific costs issues. Matthew Waszak joined the set from Temple Garden Chambers in March 2022 and adds to an impressive crop of juniors that includes regular sole costs counsel George McDonald, and Shail Patel, whose established commercial practice means he can advise on costs issues and take the lead in costs arguments as part of substantial commercial cases.
